A lockset including the credential reader further includes a controller configured to generate credential information based upon information received from the credential reader. The controller may compare the credential information to an authorized credential and transmit a grant/deny signal based upon the comparing.

TECHNICAL FIELD

The present disclosure generally relates to electronic locksets havingtouch inputs, and more particularly but not exclusively relates to suchlocksets in which the touch input is provided on a display region of thelockset.

BACKGROUND

Electronic locksets typically include some form of credential readingdevice on the outer side of the door such that a user can present acredential to cause the lockset to unlock. While certain credentialreaders require presentation of a physical token (e.g., a card or afob), other credential readers are knowledge-based, and require that theuser have knowledge of a particular passcode that the user inputs to thecredential reader. Among the most popular formats for the latter type ofcredential reader is a keypad including alphanumeric buttons that theuser depresses to input the passcode. While such keypads provide afavorable functionality, it has been found that many consumers disfavorthe large and often bulky keypads from an aesthetic perspective. Forthese reasons among others, there remains a need for furtherimprovements in this technological field.

With reference to FIG. 1, illustrated therein is an access controldevice in the form of a lockset 100 according to certain embodiments.The lockset 100 is mounted to a door 80, and generally includes aninside assembly 110 mounted to an inner side 81 of the door 80, anoutside assembly 120 mounted to an outer side 82 of the door 80, achassis 130 mounted within a cutout 83 of the door 80 and connected withthe inside assembly 110 and the outside assembly 120, and a boltmechanism 140 operably connected with the chassis 130 and operable toextend beyond a swinging edge 84 of the door 80. The lockset 100 furtherincludes an electronically-operable locking mechanism 150 having alocking state and an unlocking state, and a control assembly 160operable to transition the locking mechanism 140 between the lockingstate and the unlocking state.

The inside assembly 110 includes an inside actuator 112 that is operablyconnected to the chassis 130 such that the inside actuator 112 is atleast selectively operable to actuate the bolt mechanism 140. In theillustrated form, the inside actuator 112 is provided in the form of ahandle, and more particularly as a lever. In other embodiments, theinside actuator 112 may be provided in another form, such as that of aknob, a thumbturn, or a pushbar mechanism. The inside assembly 110further includes a lock state selector 114. In certain forms, the lockstate selector 114 may be a mechanical lock state selector thatphysically drives the locking mechanism 150 between its locking stateand its unlocking state. In other forms, the lock state selector 114 maybe an electronic lock state selector that is in communication with thecontrol assembly 160 and is operable to cause the control assembly 160to transition the locking mechanism 150 between its locking state andits unlocking state.

The outside assembly 120 includes an outside actuator 122 that isoperably connected to the chassis 130 such that the outside actuator 122is selectively operable to actuate the bolt mechanism 140. In theillustrated form, the outside actuator 122 is provided in the form of ahandle, and more particularly as a lever. In other embodiments, theoutside actuator 122 may be provided in another form, such as that of aknob, a thumbturn, or a lock cylinder. The outside assembly 120 mayfurther include a credential reader 124 in communication with thecontrol assembly 160. Certain exemplary forms of the credential reader124 are provided herein. During operation of the lockset 100,presentation of an appropriate credential to the credential reader 124(e.g., by inputting a code and/or presenting a gesture) causes thecontrol assembly 160 to transition the locking mechanism 150 from thelocked state to the unlocked state to selectively permit actuation ofthe bolt mechanism 140 by the outside actuator 122.

The chassis 130 is mounted within the door cutout 83 and at leastselectively connects each of the actuators 112, 122 with the boltmechanism 140. The chassis 130 may, for example, take the form of amortise-format chassis, a cylindrical-format chassis, or atubular-format chassis, the features of which will be readily apparentto those skilled in the art. The chassis 130 has a locked state and anunlocked state. In the unlocked state, the chassis 130 maintains thebolt mechanism 140 in a retracted state and/or permits the outsideassembly 120 to retract the bolt mechanism 140. In the locked state, thechassis 130 maintains the bolt mechanism 140 in an extended state and/orprevents the outside assembly 120 from retracting the bolt mechanism140. The chassis 130 may be transitioned between the locked state andthe unlocked state by the electronic locking mechanism 150.

The bolt mechanism 140 includes a bolt 142 having an extended positionand a retracted position. With the bolt 142 in the extended position andthe door 80 in the closed position, the bolt 142 extends into thedoorframe and retains the door 80 in the closed position. When the bolt142 is retracted, the door 80 is free to move to the open position. Inthe illustrated form, the bolt mechanism 140 is provided in the form ofa latchbolt mechanism, and includes a spring-loaded latchbolt 142 thatis biased toward its extended position. In other forms, the boltmechanism 140 may be provided in the form of a deadbolt mechanism, andmay include a bolt 142 in the form of a deadlocking deadbolt.Additionally, while the illustrated bolt mechanism 140 is providedadjacent the chassis 130, it is also contemplated that the boltmechanism 140 may be positioned remotely from the chassis 130.

The electronic locking mechanism 150 may be mounted within the chassis130, and has an unlocking state in which the door 80 can be opened fromthe outer side 82 (e.g., by operating the outside actuator 122 and/orpulling the door 80 toward its open position), and a locking state inwhich the door 80 cannot be opened from the outer side 82. In theillustrated form, the locking mechanism 150 prevents the outsideactuator 122 from actuating the bolt mechanism 140 when in the lockingstate, and permits the outside actuator 122 to actuate the boltmechanism 140 when in the unlocking state. In other forms, the lockingmechanism 150 may retract the bolt 142 when transitioned from thelocking state to the unlocking state, and may extend the bolt 142 whentransitioned from the unlocking state to the unlocking state.

With additional reference to FIG. 2, the electronic locking mechanism150 includes a locking member 152 having a locking position and anunlocking position, and an electronic actuator 154 operable to drive thelocking member 152 between the locking position and the unlockingposition to thereby adjust the locked/unlocked state of the lockset 100.In certain forms, the locking member 152 may be configured toselectively prevent the outside actuator 122 from retracting the bolt142. As one example, the outside actuator 122 may be operably coupledwith the bolt mechanism 140 such that rotation of the actuator 122retracts the bolt 142, and the locking member 152 may prevent rotationof the actuator 122 when in the locking position. As another example,the outside actuator 122 may be selectively coupled with the boltmechanism 140 via the locking member 152. In such forms, rotation of theactuator 122 may cause retraction of the bolt 142 when the lockingmember 152 is in its unlocking position, and the actuator 122 mayfreewheel without causing retraction of the bolt 142 when the lockingmember 152 is in its locking position. In further embodiments, thelocking member 152 may be provided as the bolt 142 such that the lockingmechanism 150 drives the bolt 142 between its extended locking positionand its retracted unlocking position without requiring operation ofeither manual actuator 112, 122.

The control assembly 160 includes a controller 162, and may furtherinclude an onboard power supply 166 and/or a wireless transceiver 164configured to facilitate communication between the controller 162 and anexternal device 190. The controller 162 is in communication with thecredential reader 124 and the locking device 150, and is configured tocontrol operation of the locking device 150 based in part uponinformation received from the credential reader 124. For example, whenan appropriate credential is presented to the credential reader 124, thecontroller 162 may transmit an unlock signal that transitions thelocking device 150 from the locking state to the unlocking state,thereby permitting opening of the door 80 from the outer side 82thereof.

With additional reference to FIG. 3, illustrated therein is a credentialreader 200 according to certain embodiments, which may be utilized asthe credential reader 124 in the lockset 100. The credential reader 200includes a touch-sensitive track pad 210 configured to generatecoordinate information relating to the location at which it has beentouched by a user's finger. The track pad 210 may, for example, beprovided in the form of a capacitive touch pad. The track pad 210 mayhave a plurality of zones 211-219 defined thereon. While the illustratedtrack pad 210 defines nine discrete zones 211-219, it is to beappreciated that more or fewer zones may be utilized, and that some orall of the zones may define continuous regions with adjacent zones. Incertain forms, the track pad 210 may include landmarks denoting notablefeatures (e.g., the center and/or boundaries) of one or more zones. Incertain forms, the track pad 210 may be a non-displaying track pad. Inother embodiments, the track pad 210 may include features by which thetrack pad 210 can selectively display information, such as an LED array.

The track pad 210 is sensitive to the touch of a human finger, and isconfigured to generate information relating to the location in which itis being touched. In the illustrated form, the track pad 210 isconfigured to generate information relating to the zone being touched.For example, the track pad 210 may generate coordinate informationrelating to the X- and Y-coordinates of the contact, and the controller162 may compare the coordinate information to known boundaries of thezones 211-219 to determine the zone within which the touch is located.For example, in the event that the user traces an L-shaped gesture alongthe track pad (FIG. 4), the controller 162 may determine that zones havebeen touched in the sequence of 211, 214, 217, 218, 219, therebygenerating credential information relating to such a sequence.

In certain forms, the controller 162 may utilize the coordinateinformation from the track pad 210 to generate credential informationthat is independent of the location of the track pad on which thegesture is made. To take a simple example, the controller 162 mayinterpret the sequence 211, 212, 213 as a gesture of a horizontal lineextending from left to right, and generate the credential information ascorresponding to such a gesture. When a horizontal line is traced fromleft to right along another portion of the track pad (e.g., in thesequence 214, 215, 216), the controller 162 may interpret suchcoordinate information as corresponding to the same gesture as thesequence of 211, 212, 213. Thus, in certain forms, the controller 162may be agnostic as to the gesture's location on the track pad 210. Bytaking more zones into account, significantly more complex gestures maybe possible, and the controller 162 may utilize known patternrecognition techniques to distinguish between such gestures.

In certain forms, the controller 162 may be configured to distinguishbetween gestures and discrete touches using the coordinate informationreceived from the credential reader 200. The controller 162 may thusgenerate the credential information to include both gesture informationand zone information. In certain forms, the gesture information may belocation-agnostic while the zone information is location-dependent. Forexample, an authorized credential may include a left-to-right swipe onany location of the track pad 210 followed by touching the zones 215,211, 213 in sequence. As noted above, the track pad 210 may includelandmarks indicating features of the zones, which may facilitate theuser's touching of the track pad 210 in the appropriate zones.

As should be evident from the foregoing description, the credentialreader 200 provides an alternative to traditional knowledge-basedcredential readers such as keypads. More particularly, the credentialreader 200 facilitates the creation of knowledge-based credentials thatinclude both gestures and sequences. In contrast, traditionalkeypad-type credential readers allow only for sequence-basedcredentials, such as PIN codes. In providing gestures as an additionaloption, the credential reader 200 may increase the number of possiblecredentials while maintaining the touch-based input to which users havebecome accustomed.

With additional reference to FIG. 5, illustrated therein is at least aportion of an outside assembly 300, which may be included in orconstitute the outside assembly 120 of the lockset 100. The outsideassembly 300 includes a generally circular housing in the form of ashroud 302, a lock cylinder 304 mounted in the shroud 302, and acredential reader 310 according to certain embodiments.

With additional reference to FIG. 6, the credential reader 310 includesa touch-sensitive display 312 having a plurality of touch sensitivedisplay regions, including a first touch-sensitive display regionconfigured to display a code character 322. The touch-sensitive display312 may include at least one additional touch-sensitive display region.In the illustrated form, the touch-sensitive display 312 includes threetouch-sensitive display regions 320, 330, 340. In certain embodiments,the display regions 320, 330, 340 may be contiguous, while in otherembodiments the display regions 320, 330, 340 may be discrete.

The touch-sensitive display 312 may, for example, include a dot matrixlight emitting diode (LED) display 313. As described herein, such a dotmatrix style display has the advantage of facilitating the display ofvarious feedback messages and icons. In certain embodiments, thetouch-sensitive display 312 may include separate switches 325, 335, 345(e.g., resistive, tactile or capacitive switches) for eachtouch-sensitive display region 320, 330, 340. In certain embodiments,the touch-sensitive display 312 may include a capacitive sense array 314operable to distinguish between swipes in a first direction (e.g.,left-to-right), swipes in a second direction (e.g., right-to-left), andtaps or discrete touches on the various display regions 320, 330, 340.

Each of the display regions is operable to selectively display indiciathat facilitate entry of a code to the credential reader 310. In theillustrated form, the first display region 320 is located between thesecond display region 330 and the third display region 340, and isconfigured to display a code character 322 such as a code number 323.The second display region 330 is positioned to the left of the firstdisplay region 320 and displays an indicium 332 indicating that touchingthe first display region 320 adjusts the displayed code character 322 ina first manner. For example, the indicium 332 may comprise a down arrowor a left arrow 333 indicating that touching the second display region330 decrements the displayed code number 323. The third display region340 is positioned to the right of the first display region 320 anddisplays an indicium indicating that touching the third display region340 adjusts the code character 322 in a second manner opposite the firstmanner. For example, the indicium 342 may comprise an up arrow or aright arrow 343 indicating that touching the third display region 340increments the displayed code number 323.

While the code character 322 of the illustrated embodiment is providedin the form of a code number 323, it is also contemplated that the codecharacter 322 may take another form, such as that of a letter or anon-alphanumeric symbol. Thus, while certain descriptions herein maymake reference to incrementing, decrementing, and selecting thedisplayed code number 323, those skilled in the art will readilyappreciate that similar actions may be performed using code characters322 of another form (e.g., letters and/or symbols).

During normal operation, the credential reader 310 may begin in a sleepmode in which the display 312 is turned off to save battery power. Thecredential reader 310 may awaken in response to a waking touch, whichmay, for example, be provided at one or another of the touch-sensitivedisplay regions 320, 330, 340. Upon waking, the credential reader 310 isconfigured to display the displayed code character 322 at the firsttouch-sensitive display region 320, and to select the displayed codecharacter 322 in response to being touched in a first touching manner.For example, the credential reader 310 may select the displayed codecharacter 322 in response to the first touch-sensitive display region320 being tapped. Upon selecting the displayed code character 322, thecredential reader transmits to the controller 162 code characterinformation relating to the selected code character. As describedherein, the credential reader 310 may further cause additional indiciato be displayed on the touch-sensitive display 312 to confirm selectionof the code character 322.

The credential reader 310 is also configured to adjust the displayedcode character 322 in a first adjusting manner when the touch-sensitivedisplay 312 is touched in a second touching manner different from thefirst touching manner. As one example, the credential reader 310 mayincrement the displayed code number 313 when the second touch-sensitivedisplay region 330 is tapped. As another example, the credential reader310 may increment the displayed code number 313 when the capacitivesense region 314 indicates a swipe in the first swipe direction (e.g.,the left-to-right direction).

The credential reader 310 may further be configured to adjust thedisplayed code character 322 in a second adjusting manner opposite thefirst adjusting manner when the touch-sensitive display 312 is touchedin a third touching manner different from the first and second touchingmanners. As one example, the credential reader 310 may decrement thedisplayed code number 313 when the third touch-sensitive display region340 is tapped. As another example, the credential reader 310 maydecrement the displayed code number 313 when the capacitive sense region314 indicates a swipe in the second swipe direction (e.g., theright-to-left direction).

The credential reader 310 is in communication with the controller 162,and is configured to transmit to the controller 162 code characterinformation relating to the displayed code character 322 in response tothe displayed code character 322 being selected. The credential reader310 may further cause the touch-sensitive display 312 to display indiciaindicating to the user that the displayed code character 322 has beensuccessfully selected. For example, the credential reader 310 may causethe second and third display regions 330, 340 to display check marks.

The controller 162 is configured to generate credential informationbased upon the code character information received from the credentialreader 310. For example, when the code number “9” is selected at thecredential reader 310, the controller 162 adds “9” to the credentialinformation, thereby generating or modifying a credential code. Uponselecting the displayed code character 322, the credential reader 310may display indicia indicating that the displayed code character 322 hassuccessfully been selected, and in certain forms may cause the displayedcode character 322 to revert to a default code character. For example,where code numerals are used, the displayed code numeral 323 may revertto the “5” number, thereby facilitating selection of the next codenumeral 323.

Once a sufficient number of code characters 322 have been added to thecredential information (e.g., four code characters 322), the controller162 may compare the generated credential information to authorizedcredential information. If the credential information matches theauthorized credential, the controller 162 transmits the unlock signal tothe locking mechanism 150, thereby unlocking the lockset 100. Thecredential reader 310 may cause the touch-sensitive display 312 todisplay unlocking indicia indicating that the lockset 100 hassuccessfully been unlocked. If the credential information does not matchthe authorized credential, the controller 162 does not transmit theunlock signal to the locking mechanism 150, and the lockset 100 remainslocked. The credential reader 310 may cause the touch-sensitive display312 to display failure indicia indicating that the lockset 100 has notbeen unlocked.

As noted above, the lockset 100 may include a wireless transceiver 164to facilitate communication between the controller 162 and an externaldevice 190, such as a mobile device. In certain embodiments, theexternal device 190 may be utilized to commission and/or configure thecredential reader 310, and the credential reader 310 may be configuredto display indicia relating to such commissioning and/or configuring. Incertain embodiments, at least some of the below-described steps ofcommissioning and configuring may be performed at the credential reader310 without requiring connection to the external device 190.

With additional reference to FIG. 7, illustrated therein are examples ofindicia 400 that may be displayed on the touch-sensitive display 312during operation of the lockset 100. As will be appreciated, at leastsome of the indicia 400 may be displayed on the touch-sensitive display312 during normal operation of the lockset 100, and at least some of theindicia 400 may be displayed on the touch-sensitive display duringcommissioning and/or configuring of the lockset 100.

Indicia 402 and indicia 404 each relate to the adjustment of the codecharacter 322, and include the above-described code character 322 andselection arrows. Indicia 402/404 may, for example, be displayed tofacilitate adjustment and selection of the code character 322.

Indicia 406 relates to selection of the code character, and include thedisplayed code character 322 and check marks. Indicia 406 may, forexample, be displayed to indicate that the displayed code character 322has successfully been selected and added to the credential codeinformation.

Indicia 408 relates to the locked state and may, for example, bedisplayed to indicate that the lockset 100 has returned to its lockingstate following a successful unlocking operation.

Indicia 410 relates to the unlocked state and may, for example, bedisplayed to indicate that the lockset 100 has successfully beenunlocked and that the door can be opened.

Indicia 412 relates to a low-battery state and may, for example, bedisplayed when the controller 162 detects that the onboard power supply166 is running low.

Indicia 414 relates to adding a user to a list of authorized users. Theindicia 414 may, for example, be displayed during a commissioningoperation in which a new user credential is being added to the list ofauthorized credentials.

Indicia 416 relates to removing a user from the list of authorizedusers. The indicia 414 may, for example, be displayed during acommissioning operation in which a user credential is being removed fromthe list of authorized credentials.

Indicia 418 relates to a failure to transition to the unlocked state,and indicates that the lockset 100 remains locked. The indicia 418 may,for example, be displayed in response to the inputted credential failingto match an authorized credential in the list of authorized credentials.

Indicia 420 relates to a successful transition to the unlocked state andmay, for example, be displayed when the lockset 100 has successfullybeen unlocked by operation of the credential reader 310.

Indicia 422 relates to a commissioning operation in which all user codesare to be removed from the list of authorized credentials, and may bedisplayed during such an operation.

Indicia 424 are confirmation indicia and may, for example, be displayedwhen confirmation of an action is sought. By way of example, theconfirmation indicia 424 may be displayed after displaying indicia 422to confirm that the user truly desires to erase all stored codes,thereby hindering accidental erasure.

Indicia 426 and 428 relate to automatic locking. In certain embodiments,the lockset 100 may be operable to automatically return to the lockedstate a predetermined amount of time after being unlocked by thecredential reader 310. In such forms, the credential reader 310 mayselectively display indicia 426 to indicate that such automaticrelocking is enabled, and may selectively display indicia 428 toindicate that such automatic relocking is disabled.

Indicia 430 relates to a vacation mode, and may be selectively displayedto indicate that the lockset 100 is operating in such a vacation mode.While operating in vacation mode, operation of the lock by thecredential reader 310 may be disabled such that the user must use aphysical key to operate the lockset 100 from the outer side of the door.

Indicia 432 includes return indicia, and may be displayed when tappingthe touch-sensitive display 312 will cause the credential reader 310 toreturn to a higher-level menu or abort the commissioning and/orconfiguring process.

Those skilled in the art will readily recognize that the illustratedindicia 400 among others may be displayed during normal operation of thelockset 100 and/or during the commissioning and/or configuring of thelockset 100. To take one example, upon entry of a configure-authorizedcode, the credential reader 310 may enter a configure operation. Theconfigure operation may begin by displaying the add user indicia 414,and touching the display 312 in the first manner (e.g. by tapping thefirst region 320) may cause the credential reader 310 to enter auser-adding process in which a new code is added to the list ofauthorized codes. In response to the display 312 being touched in thethird touching manner (e.g., by tapping the region 330 or swiping to theleft), the credential reader 310 may display the return indicia 432.Conversely, touching the display 312 in the second manner (e.g., bytapping the region 340 or swiping to the right) may cause the credentialreader 310 to display the remove user indicia 416.

While the remove user indicia 416 is displayed, touching the display 312in the first manner may cause the credential reader 310 to enter auser-removing process in which an existing code is removed from the listof authorized codes. In response to the display 312 being touched in thethird touching manner, the credential reader 310 may again display theadd user indicia 414. In response to the display 312 being touched inthe second touching manner, the credential reader 310 may cause theremove all users indicia 422 to be displayed.

While the remove all users indicia 422 is displayed, touching thedisplay 312 in the first manner may cause the credential reader 310 todisplay the confirmation indicia 424. Again touching the display 312 inthe first manner may cause the credential reader 310 to remove allunlock-authorized codes. Touching the display 312 in the second mannerand/or the third manner may cause the credential reader 310 to onceagain display the remove all users indicia 422. At this stage, touchingthe display 312 in the third manner may cause the credential reader 310to display the remove single user indicia 416.

With the remove all users indicia 422 displayed, touching the display inthe second manner may cause the credential reader 310 to display theappropriate one of the automatic locking indicia 426, 428. From thisstage, touching the display 312 in the first manner may cause thecontroller 162 to transition the lockset 100 between an automaticlocking state and a non-automatic locking state, thereby causing theother indicia 426, 428 to be displayed. Touching the display 312 in thethird manner may cause the credential reader 310 to display the removeall users indicia 422, and touching the display 312 in the second mannermay cause the credential reader 310 to display the vacation mode indicia430.

With the vacation mode indicia 430 displayed, touching the display 312in the first manner may cause the lockset 100 to transition between avacation mode and a standard operating mode. Touching the display 312 inthe third manner may cause the credential reader 310 to display theappropriate one of the automatic locking indicia 426, 428, and touchingthe display 312 in the second manner may cause the credential reader 310to display the return indicia 432.

Although an example order in which the indicia 400 may be displayed hasbeen described, it is to be appreciated that other orderings are alsocontemplated. It should also be appreciated that one or more of theabove-described indicia 400 may not necessarily be displayed, and thatadditional or alternative indicia not specifically illustrated in FIG. 7may be displayed. For example, in embodiments in which the lockset 100does not have a vacation mode, the vacation mode indicia 430 may notnecessarily be displayed. As another example, although not specificallyillustrated in FIG. 7, the indicia 400 may include indicia indicatingthe strength of a wireless communication connection established by thewireless transceiver 164. It should also be appreciated that while theconfirmation indicia 424 has been described only in association with theremove all users operation, the confirmation indicia 424 may be utilizedin association with other operations.

As should be evident from the foregoing, the dot matrix LED array 313utilized in the illustrated embodiment provides appreciable flexibilityin facilitating the operation of the credential reader 310, both in thenormal mode and the commission/configure mode. The LED array 313 alsoprovides the advantage of being self-illuminated, thereby obviating theneed for additional illumination devices when the credential reader 310is operated in dark environments. In certain forms, the LED array 313may be a printed-on-film LED array, which may provide for exceptionallythin forms of the touch-sensitive display 312. It has been found thatsuch embodiments may integrate the switches, the illuminating areas, andthe circuitry within a thickness of less than twenty thousandths of oneinch. Such a thin display 312 allows the trim cover to sandwich thedisplay 312 between the deadbolt shroud 302 and the cover, leaving openareas for the user to see and touch the switches. In other forms,standard discrete components of a seven segment display and illuminatedtact switches could be wired together to achieve the same functionality,but the thickness may be greater.

Due to the small footprint of the touch-sensitive display 312, thecredential reader 310 is able to be incorporated in deadbolt assemblieshaving standard dimensions. For example, the credential reader 310 mayfit within the decorative trim cover of the shroud 302, which provides avery discreet aesthetic to minimize the visible portion of the codeentry user interface. This approach may also save manufacturing costssince it does not require a separate escutcheon to contain a keypad. Italso provides flexibility for the aesthetic style of the lockset 100, asthe user need only select the aesthetic of the trim cover. Due to thelow profile of the credential reader 310, it does not detract from theoverall aesthetic of the lock in the manner that traditional keypadshave been known to do.

One additional drawback of conventional keypad mechanisms is that withheavy use, fingerprint residue or wearing of the most-used keys may giveunauthorized persons clues as to which numbers are included in theunlock code, thereby decreasing security. In contrast, the credentialreader 310 displays all code characters at one location, whicheliminates the above-noted drawback of conventional keypads.

With additional reference to FIG. 8, an exemplary process 500 that maybe performed using the lockset 100 and one or both of the credentialreaders 200, 310 is illustrated. Operations illustrated for theprocesses in the present application are understood to be examples only,and operations may be combined or divided, and added or removed, as wellas re-ordered in whole or in part, unless explicitly stated to thecontrary. Unless specified to the contrary, it is contemplated thatcertain operations or steps performed in the process 400 may beperformed wholly by the credential reader 124 (e.g., the credentialreader 200 and/or the credential reader 310), the locking mechanism 150,the control assembly 160, and/or the external device 190, or that theoperations or steps may be distributed among one or more of the elementsand/or additional devices or systems that are not specificallyillustrated in FIGS. 1-7.

The process 500 includes block 510, which generally involves generatingswipe/tap information 511 using the credential reader 124. For example,block 510 may involve generating the swipe/tap information 511 basedupon swipes and/or taps on the track pad 210 and/or the touch-sensitivedisplay region 312. Block 510 may further include waking the credentialreader 124 and/or the controller 162 in response to the initialtap/swipe, for example in embodiments in which the credential reader 124and/or the controller 162 is operable in a low-power sleep mode. Asnoted above, at least some embodiments of the above-described track pad210 and touch-sensitive display 312 are operable to distinguish betweentouches and swipes. Thus, in at least some embodiments, the swipe/tapinformation 511 may include both swipe information 512 and tapinformation 513, wherein the controller 162 is capable of distinguishingbetween the touches and the swipes.

The process 500 also includes block 520, which generally involvesgenerating credential information 521 based upon the swipe/tapinformation 511. For example, in embodiments in which the credentialreader 124 is provided in the form of the credential reader 200, thecredential information 521 may include information representative of theswipes and the taps, one or both of which may be location-agnostic orlocation-dependent. In embodiments in which the credential reader 124 isprovided in the form of the credential reader 310, the controller 162may alter the displayed code character 322 in response to swipes and/ortaps of one type (e.g., taps on the second and third display regions230, 240), and generate the credential information 521 to include thedisplayed code character 322 in response to taps of a second type (e.g.,taps on the first display region 220).

The process 500 further includes block 530, which generally involvestransmitting a signal 531 based upon the credential information 521. Forexample, block 530 may involve comparing the credential information 521to an authorized credential 532, and transmitting a grant/deny signal531 based upon the comparing. In such forms, block 530 may involvetransmitting the grant/deny signal 531 as a grant signal when thecredential information 521 corresponds to an authorized credential 532,and transmitting the grant/deny signal 531 as a deny signal when thecredential information 521 does not correspond to an authorizedcredential 532.

The process further includes block 540, which generally involvesperforming an action 541 based upon the signal 531. For example, inembodiments in which the signal 531 is provided as a grant/deny signal,block 540 may involve operating the locking mechanism 150 to unlock thelockset 100 in response to the grant signal, and may involve notoperating the locking mechanism 150 such that the lockset 100 remainslocked in response to the deny signal. Block 540 may further includeperforming additional or alternative actions in response to thegrant/deny signal 531. For example, in embodiments in which thecredential reader 124 is provided as the credential reader, block 540may involve displaying the grant indicia 420 in response to the grantsignal, and displaying the deny indicia 418 in response to the denysignal.
